f.lux 22.0

f.lux is a mobile version of the utility for adjusting the color gamut of the display of your Android device depending on the time of day, thanks to which you can significantly reduce eye strain when working in the evening and at night by reducing the blue color in the color spectrum of the display at the system level.

As you know, the human eye is very sensitive to the brightness of the screen, and the brighter the screen of the device relative to the surrounding background, the harder it is for the eyes to perceive the image on it. But in addition to brightness, color temperature also plays an important role. Probably, everyone noticed that at night black text on a bright white background hurts the eyes very much, and during the day such text is read much more comfortably. f.lux allows you to smooth out such sharpness, reducing the proportion of blue in the color spectrum of the screen in the evening. At night, the emphasis is placed on warm tones that are more suitable for artificial lighting. Cold colors are set during the day, as they are more organic in relation to daylight. Thanks to such a useful function, the load on vision is significantly reduced.

At the moment, f.lux is in beta testing, so there may be instability in the program. The developers also warn about incompatibility with some Samsung mobile devices. Superuser (ROOT) rights are required for the program to work.
